Abstract:

BACKGROUND: Up to date, thestudies regarding the construction of herpes simplex virus 1-thymidine kinase (HSV1-TK) and enhanced green fluorescent protein (EGFP) reporter gene co-expression vector and its expression in mouse bone marrow mesenchymal stem cells are few. OBJECTIVE: To construct a pHSV1-TK- IRES2-EGFP eukaryotic vector, and to observe the expression of HSV1-TK in mouse bone marrow mesenchymal stem cells. 
METHODS: The HSV1-TK cDNA fragments were obtained by polymerase chain reaction (PCR) from pHSV106 and Bgl Ⅱ, Sal Ⅰ two restriction sites were added, after T vector cloning, the recombinant plasmid pHSV1-TK/18T was digested by two restrictive endonucleases, and then HSV1-TK cDNA was collected and recombined with eukaryotic vector pIRES2-EGFP by using gene recombination technique. The recombinant plasmid pHSV1-TK- IRES2-EGFP was transfected into mouse bone marrow mesenchymal stem cells in vitro with lipofectamine transfection reagent.
RESULTS AND CONCLUSION: A length of 1 130 bp with Bgl Ⅱ and Sal Ⅰ target gene sequences was obtained by PCR. And the pHSV1-TK- IRES2-EGFP expression plasmid was constructed successfully. The TK/GFP green fluorescent protein was detected after transfection. At the same time, the expression of HSV1-TK mRNA was determined. The eukaryotic vector pHSV1-TK- IRES2-EGFP was successfully constructed, and effectively expressed HSV1-TK mRNA in mouse bone marrow mesenchymal stem cells in vitro.
